- Description
The Schneider Electric SR3XT61BD is a discrete I/O extension module for the Zelio Logic SR3 range, adding 6 I/O (4 discrete inputs, 2 relay outputs) at 24 V DC to a base smart relay. It mounts on the same DIN rail as the base unit for industrial and building-services applications needing a small additional I/O count.

Selection Notes
The SR3XT61BD is the smallest Zelio Logic SR3 extension module, adding just 4 discrete inputs and 2 relay outputs (8 A each) to a 24 V DC base unit — pick it over the SR3XT141BD or SR3XT101BD when the application only needs a handful of extra points and board space is tight. It targets both industrial and building-services panels, per Schneider's stated application scope.
